Abstract:
A method for the differentiation of illicit cocaine samples by HPLC/PDAD was presented. By this technique, the determination of the aliquots of cis- and trans-cinnamoylcocaine in relation to cocaine as well as the determination of minor alkaloids such as tropacocaine, norcocaine, N-formylcocaine and N-benzoylmethylecgonine as additional "finger-prints" proved to be a practical and always reproducible tool.
